Cookie Policy | SATs Arcade

1. What Are Cookies?

Cookies are small text files placed on your device by websites you visit. They are widely used to make websites work, or work more efficiently, and to provide information to website owners.

SATs Arcade primarily uses browser local storage rather than traditional cookies. Local storage works similarly — data is stored in your browser — but it is not automatically sent to our server with every request, making it more efficient for an app like ours.

2. What We Use and Why

We categorise our use of browser storage into three types:

Strictly Necessary

Cannot be disabled

These are essential for the service to function. Without them you cannot log in or use the app.

Key / Name	Purpose	Type	Expires
sats-arcade-auth-token	Keeps you logged in between sessions	Local storage	On logout / 30 days
sats-arcade-parent-pin-*	Remembers that a parent has entered their PIN in the current browser session, so they don't have to re-enter it on every page	Session storage	When browser tab closes
sats-arcade-cookie-consent	Records that you have acknowledged our cookie banner	Local storage	Indefinitely (until cleared)

Functional (Preferences)

Required for core functionality

These remember your preferences to give you a better experience. Disabling them means your settings won't be saved between sessions.

Key / Name	Purpose	Type	Expires
sats-arcade-accessibility	Saves your accessibility settings: dark mode, font size, dyslexia-friendly font, colour-blind mode, reduced motion, text-to-speech	Local storage	Indefinitely (until cleared)
sats-arcade-selected-profile	Remembers which child profile was last active	Local storage	Indefinitely (until cleared)
sats-arcade-sound-*	Saves sound effects and volume preferences	Local storage	Indefinitely (until cleared)

Analytics & Attribution

We use Google Analytics 4 (GA4) and PostHog to understand how visitors use SATs Arcade — for example, which pages are popular and where users encounter problems. Both services may set cookies or use browser storage to distinguish unique visitors. Data is used solely to improve the product and is not sold to third parties.

Key / Name	Purpose	Type	Expires
_ga / _ga_*	Google Analytics 4 — distinguishes unique visitors and tracks page views	Cookie	Up to 2 years
ph_*	PostHog — anonymous product analytics (autocapture disabled, inputs masked)	Cookie / Local storage	Up to 1 year

When you first register, we also record the URL parameters (e.g. utm_source, utm_campaign) and the referring website that brought you to SATs Arcade. This data is stored in our database against your account — not as a cookie — and is used to understand which marketing channels are effective. It is not shared with third parties.

We do not use Meta Pixel or any advertising tracking scripts.

3. Third-Party Cookies

The following third-party services may set cookies when you use SATs Arcade:

Google Analytics 4 — analytics cookies to help us understand site usage. Governed by Google's Privacy Policy.
PostHog — product analytics cookies (EU-hosted). Governed by PostHog's Privacy Policy.
Stripe — may set cookies during the checkout process. Governed by Stripe's Privacy Policy.

We do not use any third-party advertising or retargeting cookies.

4. How to Control Cookies & Local Storage

You can control and/or delete local storage data at any time through your browser settings. Here's how in common browsers:

Chrome: Settings → Privacy and security → Clear browsing data → Cached images and files / Cookies and other site data
Firefox: Settings → Privacy & Security → Cookies and Site Data → Clear Data
Safari: Preferences → Privacy → Manage Website Data
Edge: Settings → Cookies and site permissions → Manage and delete cookies and site data

Please note: Clearing browser storage for SATs Arcade will log you out and reset your local preferences (dark mode, font settings, etc.). Your account data and progress are stored on our servers and will not be affected.

5. Changes to This Policy

We may update this Cookie Policy when we add new features or third-party services that involve new storage use. We will update the "last updated" date and, for significant changes, notify you in the app.
